Activated microglia are considered to play important roles in degenerative processes of midbrain dopaminergic neurons. Here we examined mechanisms of neurotoxicity of thrombin, a protease known to trigger microglial activation, in organotypic midbrain slice cultures. Thrombin induced a progressive decline in the number of dopaminergic neurons, an increase(More)
Interferon-gamma (IFN-gamma)/lipopolysaccharide (LPS) induces delayed dopaminergic neuron loss in midbrain slice cultures, because of nitric oxide production resulting from p38 mitogen-activated protein kinase (p38 MAPK)-dependent induction of inducible nitric oxide synthase (iNOS). In this study, we show that inhibition of c-Jun N-terminal kinase (JNK),(More)
